Important features of crystal field theory
Witryna6 Conclusions. The crystal-field and transition-intensity models described in this chapter were the result of decades of development, drawing on a variety of theoretical … According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged metal cation and the negative charge on the non-bonding electrons of the ligand. The theory is developed by considering energy changes of the five degenerate d … Zobacz więcej Crystal field theory (CFT) describes the breaking of degeneracies of electron orbital states, usually d or f orbitals, due to a static electric field produced by a surrounding charge distribution (anion neighbors). … Zobacz więcej The crystal field stabilization energy (CFSE) is the stability that results from placing a transition metal ion in the crystal field generated by a set of ligands.

It is the process of the splitting of degenerate level in the presence of ligand. The difference between the energy of t2g and eg level is denoted by “Δ o ”. There are some ligands producing strong fields and causing large crystal field splitting. On the other hand, others produce very weak fields.
